Krusenstern is a lunar impact crater that lies amidst the battered terrain in the southern part of the Moon's near side. Nearly attached to the east-southeast rim is the crater Apianus. Less than one crater diameter to the southwest is the prominent Werner. Krusenstern is intruding into a large circular plain to the north designated Playfair G. Playfair itself lies to the northeast.
Krusenstern is 47 kilometers in diameter, and its walls reach a height of 1,600 meters.[1][2] Its outer rim has been heavily worn by impact erosion, leaving an irregular ring of rising ridges and an inner wall incised by impacts. A joined pair of craters, including Krusenstern A, lie along the eastern rim. The interior floor of Krusenstern is a nearly featureless plain, marked only by a few tiny craterlets.[3] The crater is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.[1]
It is named after Adam Johann von Krusenstern, an early 19th-century Baltic German explorer in Russia n service.[4][1]
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Krusenstern.[5]
